Figure 5b. Ganglioneuroma in an asymptomatic 57-year-old woman. (a) Axial T2-weighted (6,000/112) MR image of the left ventricle (LV) shows curvilinear areas of low signal intensity (arrowheads) in the tumor, which give it a septated appearance. The tumor had a broad base and was attached to several vertebral bodies. (b) Photograph of the cut surface of the resected specimen shows fibrous septa (arrowheads) that correspond to the curvilinear areas of low signal intensity on the T2-weighted MR image.
